DETAILED DESCRIPTION

The present invention relates to cable managers for routing cables toand from electronic equipment, such as telecommunications equipment andcomputers. One embodiment of the cable manager 10 of the presentinvention is shown in FIGS. 1-3. Cable manager 10 comprises panel 12, atleast two adjacent spaced-apart projections 14 and 15, at least one tab16 and a plurality of open C-shaped projections 17. Cable manager 10 mayoptionally include front and rear doors 18 and 20.

As shown in FIG. 1, panel 12 includes a generally rectangularconfiguration. Panel 12 comprises front and rear surfaces 22 and 24 anda number of through-holes 26. Through-holes 26 allow cables to passbetween front and rear surfaces 22 and 24 of central panel 12, andprovide bend radius control for cables passing therethrough. Panel 12may include spools (not shown) to enhance retention of cables withincable manager 10.

As best seen in FIG. 5, the at least two adjacent spaced-apartprojections 14 and 15 comprise a spine portion 13, which is secured toopposing sides A and B of panel 12. The securement employed may includea nut and bolt arrangement or the like. Other securements known to thoseof skill in the art may, however, be employed.

Projections 14 and 15 extend in a direction transverse to panel 12. Inone embodiment, projections 14 and 15 extend in a directionperpendicular to the panel. In another embodiment, projections 14 and 15comprise a plurality of projections positioned in a row 33 alongopposing sides of panel 12. When two or more cable managers 10 areutilized together, rows 33 of projections 14 and 15 are aligned throughthe use of pin-holes 35 and bosses 37 positioned in a matingrelationship on spine portions 13, as best seen in FIG. 6.

As shown in FIG. 4, two adjacent projections 14 and 15 define opening36. Opening 36 is positioned between a top surface 38 of one projection14 and a bottom surface 40 of another projection 15. The size of opening36 may be between about 1.0 inches and about 1.75 inches. Although otherconfigurations are suitable, the at least two adjacent projections 14and 15 are generally parallel to one another.

At least one tab 16 is connected to a distal end of the one projection14. Tab 16 extends in a direction toward bottom surface 40 of the otherprojection 15. As shown in FIG. 4, tab 16 extends beyond a midpoint 44of opening 36 defined by two adjacent projections 14 and 15. In oneembodiment, the distance d between a top surface 19 of tab 16 on oneprojection 14 and a bottom surface 40 of other projection 15 is within arange of 0.10 inches and about 0.30 inches, more particularly betweenabout 0.125 inches and about 0.275 inches. In one embodiment, d is about0.14 inches. In these embodiments, tab 16, when viewed in combinationwith projection 14 to which it is connected, forms an L-shape.

The relationship between tab 16 on one projection 14 and otherprojection 15 is advantageous. Distance d is large enough to allowcables 66 to enter opening 36, while at the same time, small enough toprevent cables from sliding off a side of projections 14 and 15.Moreover, the positioning of tab 16 on one projection 14 relative tobottom surface 40 of other projection 15 permits a user to insert amaximum number of cables into opening 36 without the cables beingpositioned next to a point corresponding to d where cables enter opening36.

Referring again to FIGS. 1-3, to further enhance cable retention, frontand rear doors 18 and 20 may be positioned in a spaced-apartrelationship with panel 12. Doors 18 and 20 may be secured to the frontand rear of cable manager 10 and may be swung open from either side ofcable manager 10. For example, as shown in FIG. 10, door 18 opens fromone side of cable manager 10. Inner surfaces 48 of front and rear doors18 and 20 comprise U-shaped channels 50 that run along a length of frontand rear doors 18 and 20. U-shaped channels 50 are adapted to engage theouter surfaces of C-shaped projections 17, which are oriented away fromopposing rows 33 of projections 14 and 15.

Each C-shaped projection 17 is integrally molded with tab 16, as shownin FIG. 7. C-shaped projection 17 comprises groove 27 and flat surface31, as best seen in FIG. 10. Groove 27 is adapted to receive a sidewallof U-shaped channel 50 so that doors 18 and 20 can swing open aboutC-shaped projections 17. This configuration optimizes the degree ofrotation of doors 18 and 20.

Further, a user may determine the positioning of doors 18 and 20. WhenU-shaped channels 50 engage C-shaped projections 17 on opposing rows 33of projections 14 and 15, doors 18 and 20 are closed. When U-shapedchannels only engage C-shaped projections 17 along one row ofprojections, doors 18 and 20 may be swung open about the engagedC-shaped projections 17. Since C-shaped projections 17 are disposed onopposing rows of projections 14 and 15, doors 18 and 20 may be swungopen in either direction.

The various components of the cable manager 10 may be made by injectionmolding, without the use of a metal backplane. For example, panel 12,rows 33 of projections 14 and 15 and doors 18 and 20 may be made asseparate plastic components and then assembled through methods describedhereinabove.

In use, cable manager 10 may be mounted to rack 52, as shown in FIG. 1.The term rack, as used herein, means a device used to support or houseelectronic equipment. A variety of racks may be employed, includingracks that conform to the WECO and EIA standards known to those of skillin the art. Such racks comprise a plurality of rack mounting apertures54 along a vertical member 56, as best seen in FIG. 7. Cable manager 10may be secured to rack 52 through methods known to those of skill in theart.

After cable manager 10 has been mounted to rack 52, a plurality ofcables 66 may be routed to and from electronic equipment. Cables 66 maybe routed through openings 36 between adjacent projections 14. Tabs 16help retain cables 66 and substantially prevent them from falling orslipping out of opening 36.

As shown in FIGS. 1 and 2, the cable manager 10 is mounted to a rack 52.The rack 52 may have various types of electrical equipment mountedthereto or otherwise situated thereon. One face of the rack may beutilized to accommodate input and output lines while the opposite facemay be reserved for connecting cables for interconnecting specifiedinputs to specified outputs. In other embodiments, a rack system mayinclude several racks adjacently aligned, with the rack on one end ofthe alignment accommodating input lines and the rack on the opposite endof the alignment providing output lines. In this arrangement, the cableconnections within and between the intermediate racks may serve toconnect the inputs and outputs in the desired configuration, as well asto provide pathways to and from the intermediate electrical components.

As shown in FIGS. 5-9, the cable manager 10 is mounted to the rack 52through the use of one or more metal mounting brackets 58. The metalmounting brackets 58 are attached to a spine portion 13 of the cablemanager 10 through the use of a snap-fit. As best seen in FIG. 6, therecessed area 60 in the spine portion 13 allows the wall thickness ofthe mounting bracket 58 to remain flush with the overall thickness ofthe cable manager 10. As shown in FIG. 5, once the mounting bracket 58is fully engaged into the snap feature, the wall thickness of themounting bracket 58 would be flush to the side of the cable manager 10.In other embodiments, the metal mounting brackets 58 may be attached tospine portion 13 of the cable manager 10 utilizing a screw and bolt orother methods known in the art. The mounting brackets 58 may be made ofmaterials other than metal such as varying types of plastic or othercompounds known in the art. For installation purposes, one or morescrews 62 are threaded into rack mounting apertures 54 along a verticalmember 56 of the rack 52.

FIGS. 11-13 depict another embodiment in which two spacer members 202and 204 are utilized to increase the width W between the first portion186 and second portion 188 of the cable manager 110. The spacer members202 and 204 are preferably made of sheet metal, but may comprise anymaterial known in the art. Each of the spacer members 202 and 204contains circular through-openings 206, which are adapted to allowcables to be run through the circular through-openings 206. Further, thespacer members 202 and 204 each contain a plurality of through-holes 208adapted to engage a rivet 210. Similarly, each of the first and secondportions 186 and 188 contain a plurality of through-apertures 212adapted to engage a rivet 210. In other embodiments, the spacer membersmay contain one or more through-openings, and one or more through-holes,in any shape, configuration, or orientation known in the art. Similarly,in other embodiments, each of the first and second portions may containone or more through-apertures in any shape, configuration, ororientation known in the art.

During installation, the first and second portions 186 and 188 of thecable manager 110 are spaced a distance E apart leaving a space 214between the two portions 186 and 188. One of the spacer members 202 isplaced over and abutted against side C of the base members 190 of thetwo portions 186 and 188, while the other spacer member 204 is placedunder and abutted against side D of the base members 190 of the twoportions 186 and 188. The through-holes 208 of the spacer members 202and 204 are aligned with each other and with the through-apertures 212of the first and second portions 186 and 188. In addition, the circularthrough-openings 206 of the spacer members 202 and 204 are aligned.Rivets 210 are then run from the through-holes 208 of the spacer members202 and 204 through the apertures 212 of the first and second portions186 and 188 in order to attach the spacer members 202 and 204 to thefirst and second portions 186 and 188 of the cable manager 110. In suchmanner, the spacer members 202 and 204 increase the width W between thefirst and second portions 186 and 188 of the cable manager 110, therebyallowing for more area to run cable within the cable manager 110, andadditionally provide for increased width circular openings 206 throughwhich cable may be run.

FIG. 13 depicts ten-inch wide spacer members 202 and 204, which areattached to a cable manager 110 which would normally be six-inches widewithout the spacer members, to allow the total width W of the cablemanager 110 to be extended an additional four inches to provide extraarea to run cable within the manager 110. In other embodiments, one ormore spacer members may be utilized in varying shapes, sizes, andconfigurations. The one or more spacer members may be attached to acable manager utilizing snap-fits or any method known in the art.
